Pop'n Music 4: Append Disc

Summary

Pop'n Music 4 is one of the many titles in Konami's long-running rhythm game franchise, and the second of two "Append Discs" that require either pop'n music 2 or another Key Disc in the series in order to play. This particular release includes new music from the arcade version, and also restores the Beginner mode that has been previously removed from the home releases.
